Any type of solid or semi solid organic material of natural or synthetic origin, generally of high molecular weight with no defined melting point. Most resins are polymers.

Liaohe FCCDO is a better raw material to produce needle coke because it has a high content of aromatics, low content of asphalt and narrow distribution of molecular weight.

The invention relates to a method for continuous preparing polyethylene solution with high molecular weight, belongs to high molecular material preparation technical field.
